Regular $100 PLO game on UB, opponent is unknown. I sat down, was carddead, so this is about the first hand I play in 30 mins. I have a full buyin, opponent covers. Opponent hasn't done anything noteworthy.

I'm in the BB with [7h][4s][4d] and check after a bunch of limper. Flop comes [6s][4h]. I check, EP minbets, everyone calls, including villain in MP and I CR the pot. Villain is only caller.
Turn (pot=$33): . I bet pot, villain pushes. It's about $65 for me to call in a $135 pot.

What does he have? What does he think I have? Call or fold? Anyone check the turn?

He has 35 or 58. GIMME A HEART, T, 6, 4, or 7 DEALER!

He probably hit a straight but it's an easy call. I like your line throughout.

Yes, as per the new rule on UB since 01/01/2006 I always catch air on the river, especially against guys like this

I just wish I understood what these people are thinking in a hand like this... or at least get some read on them.
